Yah, big thanks to you Steve. This is a great thread to help some of us noobies get off the launching pad a little hehe
Oh and about my earlier question, since this program only calls for 3 days out of the week to weight train, would it be wise to only do cardio and nothing else on the other days?
My take on cardio, assuming you are not training for a marathon or the like, is to do the least amount possible while getting the results you're looking for. Those results for most of us are a mixture of energy expenditure (which translates into fat loss) and cardiovascular conditioning.
I'd start with 2-3 days of cardio per week. This can fall on days that you strength train or off days. If they are going to be on days that you strength train, save the cardio for after your strength training.
With the cardio, depending on your current conditioning.... always err on the safe side. Start out with a low intensity. As your conditioning progresses, so should your intensity. Intensity can be increased using a number of means (i.e., time, speed, incline, frequency, etc). I'd work your way up to 30 to 60 minutes of steady state work at a work rate of something like 70-85% of your age predicted VO2 max.
Once you build this general level of conditioning, you can begin toying around with other modes of cardiovascular exercise such as interval training, tempo runs, complexes, high intensity interval training, etc, etc, etc.
As a side-note, as you start moving up the spectrum of intensity as it pertains to cardiovascular exercise, you must become more cognizant of fatigue management. Things such as complexes and high intensity interval training can be just as stressful/taxing systemically on the body as a heavy bout of resistance training.
Most in here are not working out at a level intense enough to really bring fatigue management into play for the most part.... but a basic understanding that our body is not a machine is required by all IMO. It needs rest.
